<P>
The <tt>/etc/inittab</tt><A NAME="2456"> </A> has some special features that allow
<tt>init</tt><A NAME="2458"> </A> to react to special circumstances. These special
features are marked by special keywords in the third field.
Some examples:
<P>
<DL ><DT><STRONG><tt>powerwait</tt></STRONG>
<DD>
Allows <tt>init</tt><A NAME="2460"> </A> to shut the system down, when the
power fails. This assumes the use of a UPS, and software
that watches the UPS and informs <tt>init</tt><A NAME="2462"> </A> that the
power is off.
<P>
<DT><STRONG><tt>ctrlaltdel</tt></STRONG>
<DD>
Allows <tt>init</tt><A NAME="2464"> </A> to reboot the system, when the user
presses <TT>control-alt-del</TT> on the console keyboard.
Note that the system administrator can configure the
reaction to <TT>C-A-D</TT> to be something else instead,
e.g., to be ignored, if the system is in a public
location.<A NAME="tex2html37" HREF="footnode.html#2314"><IMG ALIGN=BOTTOM ALT="gif" SRC="./foot_motif.gif"></A>
<P>
<DT><STRONG><tt>sysinit</tt></STRONG>
<DD>
Command to be run when the system is booted. This command
usually cleans up <tt>/tmp</tt><A NAME="2468"> </A>, for example.
<P>
</DL>
<P>
The list above is not exhaustive. See your <em>inittab</em><A NAME="2470"> </A>(5)
manual page for all possibilities, and for details on how to use
the above ones.
